Title: Attachment for fishing-line
Inventor: FORREST NIGEL JOHN
IPC: A01K91/06
Filed: 1986-11-06
Abstract: An attachment for a fishing line to provide an element of lift at the sinker weight on retrieval comprises a vane (40) of kite-shaped platform and having a tail end (41) and a head end (42). A central spine (43) extends along the longitudinal axis of the vane (40) to a point intermediate the length thereof. A slot (44) extends along the longitudinal axis from the head end (42), the spine (43) has a central channel (45) of keyhole cross-section shape and retained therein is a wire element (46) which has a diameter larger than that of the opening. By this means, the wire element (46) may be pressed into the channel (45) whereupon it thereafter snaps into the enlarged central portion to be permanently retained. One end of the element (46) includes an elongate eye (47) formed by suitably bending the wire and the other end incorporates a circular eye (48) also formed by bending the wire. The loop (47) is for engagement with a sinker weight or with a swivel of which the other end engages a sinker weight and the eye (48) receives the line. <IMAGE>

Title: Cross-flow filtration
Inventor: DOWNING ANTHONY LEIGHTON
IPC: B01D29/00
Filed: 1986-03-12
Abstract: The filter has a spiral of, or parallel, spaced lengths of, double-ply material whose plies are seamed together along spaced, longitudinal seams to provide an array of side-by-side tubes. The filter support material is highly flexible and has a thickness not greater than 1 mm. Due to the tubular formation, the filter support has an uninterrupted filter zone of substantial area relative to the total area of the filter support; during filtration (when the filter support is under the pressure of the feed) the tube walls bulge out and the filter zone is restrained solely by tensile forces in the filter support itself. Substantial movement of the filter support is possible in the direction at right angles to its face when the pressures on either side of the filter support are equal. The filter support has many applications, but one application is when the filter is connected downstream of an aeration vessel with no intervening vessel, the concentrate outlet of the filter being connected to the aeration vessel for sludge return.

Title: Reinforcement means, method and apparatus for reinforcing substrata
Inventor: JACKSON ERIC ARTHUR
IPC: E21D21/00
Filed: 1988-06-08
Abstract: A method of reinforcing substrata e.g. in mines or buildings using a novel reinforcement bar and apparatus is described in which a reinforcement bar (10) is secured in a hole (14) in substrata e.g. by known curing resin. An end portion (18) of the bar projects through a hole (20) in a reinforcement plate (12) which is deformed to grip the bar (10) and to urge the plate (12) firmly against the substrata (16) by a presser member (24) of the tool. Head (56) of the bar (10) is gripped by complementary half collets (48, 50) which also grip a head (42) of the piston rod (40) of the setting apparatus, the half collets (48, 50) being retained in gripping engagement by the presser member (24) which is in the form of a sleeve (44). When the reinforcement plate is set in position, the head (56) is detached from the bar (10) under the applied load thus indicating that the reinforcement is adequately loaded. <IMAGE>

Title: Glazed fire-resistant screen
Inventor: BARRS ROBERT HENRY
IPC: E06B5/16
Filed: 1988-10-06
Abstract: A glazed fire-resistant screen includes a glazing panel (13) supported at its edge by a frame member (11) of rectangular steel tubing. Two strips (12) of rigid self-supporting non-combustable heat-insulating material are secured on opposite sides of the steel tubing, the edges of the strip (12) overlapping the edge of the glazing (13). Protective metal cladding (20) is secured to cover the strips (12) by means of clips (17), and sealing gaskets (22) are placed between the edges of the cladding (20) and the glazing (13). In the event of a fire on one side of the screen, the strips (12) of insulating material resists the conduction of heat through the frame, so that the screen forms a heat-resistant barrier. The edge of the glazing panel is also insulated from heat, to reduce the effect of sagging and drawing of the glazing at its edge, and therefore keep the screen intact for sometime. <IMAGE>

Title: Suction nozzle mounting for a cleaning vehicle
Inventor: BRADLEY RICHARD MAURICE
IPC: E01H1/08
Filed: 1990-06-08
Abstract: A self-propelled sweeper vehicle has a suction nozzle (22) trailed from a front-mounted downwardly extending linkage (80), and is constrained at its rear end by the connection to the suction duct (30). A linear actuator physically shifts in a lateral direction the connection of the linkage to the front of the nozzle, in response to control signals. The steering of the nozzle is related to the steering of the brush gear and/or the vehicle's steerable wheels in an automatic manner. Thus the nozzle maintains a proper relationship to the vehicle and its brush gear in an automatic manner. The steering of the brush gear itself is effected by the driver independently of the vehicle steering, whereby driver control is maximised while unswept trails are minimised. <IMAGE>

Title: Digital signal processing
Inventor: DENSHAM RODNEY HUGH
IPC: G06F17/17
Filed: 1990-11-22
Abstract: A circuit 10 for processing a digital data signal SI, such as a digital audio signal, by means of a digital control signal SC, such as that from a digitised control potentiometer, includes a signal processing section 12 and an interpolating section 14. The sampling frequency of the data signal SI is higher than that of the control signal SC and the interpolating section 14 provides an interpolated control signal SC at the data signal sampling rate. Thus each data signal sample can be processed in accordance with a corresponding interpolated control signal sample. The signal processing section 12 and the interpolating section 14 may be fabricated on a single integrated circuit. <IMAGE>
